Description:
------------
When foreach is used on a class property, Apache crashes in the Zend Optimizer.

When you assign the property to a variable and use that variable in the foreach, it doesn't crash.


Reproduce code:
---------------
<?php
class Test
{
  public $data;
  
  function __construct()
  {
    $this->data = array();
  }
}

$t = new Test();
$t->data = array('en' => 'english', 'nl' => 'dutch');
foreach($t->data as $key => $item)
{
  print_r($key);
  echo '<br />';
  print_r($item);
  echo '<br />';
}
?>

Expected result:
----------------
en
english
nl
dutch


Actual result:
--------------
